Анотация: The purpose of this study was to document abnormalities in premolar and molar teeth detected in a group of 100 equine patients. The oral cavities of standing, sedated horses were examined under fi eld conditions. Clinical dental examinations revealed a high prevalence of premolar and molar tooth lesions, with dental overgrowths present in all the animals. The high prevalence of buccal soft tissue lesions (38 percentage) present in this population was believed to be due to the high prevalence of moderate (72 percentage) and severe (8 percentage) dental overgrowths. Other abnormalities in premolar and molar teeth detected were: focal dental overgrowth (85 percentage), wolf teeth (27 percentage), ramps (12 percentage), deciduous caps (8 percentage), diastemata (4 percentage), worn teeth (7 percentage), shear mouth (1 percentage), wave mouth (2 percentage), step mouth (2 percentage), missing teeth (1 percentage) and fractured teeth (1 percentage). This study showed that many horses had dental disorders without showing any clinical signs
